![]() ![]() The results and the summary model provide the scientific basis to systematically explain crop yield variation in response to soil PAWC change across contrasting climates. A summary model incorporating the impact of soil PAWC, annual rainfall and the fraction of rainfall during growing season together could explain over 95% variations in long-term averaged wheat yield. There is a critical PAWC above which PAWC has no impact. Results show that wheat yield increased with soil PAWCs following a negative exponential curve. Users are shown how to prepare meteorological files, check soil conditions, change result variabl. What items can be fixed in batch mode Automatically update errors in models when run in BATCH MODEUPDATE YN Y Y N N Layers Parameters Can you force ModelCHECK batch mode to run a regeneration after it fixes the models Current issue, batch mode runs, fixes. In this study, we used an agricultural production systems model (APSIM) and wheat as an example to quantify crop growth and yield in response to a wide range of soil PAWCs. This video demonstrates how to set up an APSIM simulation. However, how soil PAWC interacts with rainfall to determine crop yield has not been quantified systematically. Plant available water holding capacity (PAWC) influences the efficiency of rainfall used by crops and consequently crop productivity in dryland cropping systems.
